   This constructor creates a new QuickHashIntStringHash. The size is the amount of
   bucket lists to create. The more lists there are, the less collisions you
   will have. Options are also supported.

       The options that you can pass in are: QuickHashIntStringHash::CHECK_FOR_DUPES,
       which makes sure no duplicate entries are added to the hash;
       QuickHashIntStringHash::DO_NOT_USE_ZEND_ALLOC to not use PHP&#039;s internal memory
       manager as well as one of QuickHashIntStringHash::HASHER_NO_HASH,
       QuickHashIntStringHash::HASHER_JENKINS1 or QuickHashIntStringHash::HASHER_JENKINS2.
       These last three configure which hashing algorithm to use. All options
       can be combined using bitmasks.
